The risks of semi-femtosecond surgery and full-femtosecond surgery are localized infection, corneal flap abnormality, over-correction and under-correction, and dry eyes.
1. Semi-femtosecond surgery: It should be noted that if you do not pay attention to scientific care after surgery, it may cause local infection and affect the recovery of the eye. In addition, during the convalescence period, the corneal flap may be displaced, so try to prevent the eye from being hit by external force.
2. Full femtosecond surgery: Usually, full femtosecond surgery is safer and has a low chance of complications. Some patients may have overcorrection or undercorrection problems after surgery. Secondly, if the tear film and nerves are damaged during the surgery, it will easily lead to a decrease in tears and show dry eye problems.
To summarize, semi-femtosecond surgery and full-femtosecond surgery have their own advantages and disadvantages, which need to be decided according to the patient’s own needs. It is recommended to choose regular hospitals for treatment to avoid accidents as much as possible.
